动态参数计算方法

A CALCULATION METHOD FOR KINETIC PARAMETERS

从动态参数的经典定义出发,利用扰动理论,给出了计算这些参数的一种方法。和常规做法不同,新方法中避免了共轭通量的计算。利用常用的少群理论和有关程序,算出反应堆若干扰动状态的有效倍增系数的值后,就可立即解得Λ和β_(eff)。计算中所用到的几个计算程序被组织为一个一体化程序包KPCP,并可装在微机上运行。

In the paper, a method for kinetic parameter calculation is proposed, which is started from the classical definition of kinetic parameters and developed by means of perturbation theory. Being different from the normal practice, in the new method the calculation of the adjoint neutron flux is avoided. After the effective multiplication factors related to several perturbed states of the studied reactor are obtained by the normal few group theory and relevant computer codes, the A and β_(eff) can be determined immediately. The computer codes used in the calculation have been organized together to form an integrated package and installed on personal computer.
